1. EMC (ELECTROMAGNETIC COMPATIBILITY) AND SAFETY NOTICES

IMPORTANT - PLEASE READ THIS INFORMATION BEFORE INSTALLATION AND USE

1.1. EMC

(ELECTROMAGNETIC COMPATIBILITY)
The P300 Modem Satellite Modems have been shown to comply with the following standards:
Emissions: EN 55022 Class B; Limits and methods of measurement of radio interference
characteristics of Information Technology Equipment.
Immunity: EN 50024 Information technology equipment immunity characteristics
Extensive testing has been performed to ensure that the unit meets these specifications when
configured with any or all of its available options, such as IF band, impedance, IF synthesiser step size,
data rates, etc.
To ensure that the P300 Modems will maintain compliance with these standards please ensure that the
following points are observed:
1) The equipment MUST BE OPERATED WITH ITS COVER ON AT ALL TIMES. If it is necessary
to remove the cover for any reason, then you must ensure that the cover is correctly refitted
before normal operation.
2) Damage to the front panel keyboard membrane or mechanical damage to the chassis could
invalidate compliancy. Please contact the factory if damage occurs for advice on continued
operation.
3) For the baseband data interfaces all 'D' type connectors must have grounding fingers on the
plug shell to guarantee continuous shielding. The back-shells must comply to the requirements
of VDE 0871 and FCC 20708, providing at least 40dB of attenuation from 30 MHz to 1 GHz. A
good quality cable with a continuous outer shield, correctly grounded, must be used.
4) Connections to the transmit and receive IF interfaces must be made with double screened
coaxial cable - for example RG223/U.
Installations which ignore these requirements will invalidate the compliancy to EMC
specifications.
